Abstract

An Ultra-Wideband (UWB) applicator for hyperthermia treatment of human head is developed. The system depends on the design of an array of small foot-print horn elements to allow the construction of large sized-array to surround the human-head. A waveform optimization tool is developed based on genetic algorithms to localize the energy into the tumor location. Computational analysis is performed using CST and experimental measurements are obtained using DASY5 system. Results of the field and SAR image distributions within the human head phantom illustrate the promising performance of this applicator design.
